Ontario Laboratories Information System (OLIS)
Ontario Laboratories Information System (OLIS) is a secure digital health tool that provides authorized health care providers with access to patients’ laboratory test orders and results, both past and present, from hospitals and public health and community labs through one platform.
The centralization of information enables patients’ results to follow them as they move between different care settings, from hospitals to long-term care, and enables health care providers to make more informed, timely and safe care decisions.
OLIS also reduces laboratory errors caused by illegibility, or misinterpretation of requested lab orders, improves the turnaround time for lab results and enables patient orders and results to be added directly into an Electronic Medical Record (EMR).
